specific Embodiment

[0045] The implementation process of embodiment 1-12 is shown in the table below:

[0046]

Embodiment 1

[0047] Filling gas in embodiment 1 is air, and the sample that injects in the glass container 12 is distilled water, after placing the sample to be irradiated for 8 days, the sample to be irradiated is connected to the gas chromatograph, and its gas chromatogram is as follows image 3 Shown: Gas chromatography shows that the micro-area of ​​hydrogen gas (microvolt*second) is 263.3, and the concentration in the air is 0.054%. After standardization, the volume of hydrogen gas in the air sample is 0.000101ml (under one standard atmospheric pressure), and the hydrogen gas is Mass is 9.1×10 -9 g, the number of moles of hydrogen is 4.55×10 -9 mol. This amount of hydrogen is the amount of hydrogen in the gas above the distilled water sample in the glass container that has been placed for 8 days.

Embodiment 2

[0048] The gas chromatogram that embodiment 2 obtains, as Figure 4 As shown, the hydrogen microarea (microvolt*second) in the radiation gas is 122535.3, and the hydrogen concentration is 22.29%. After standardization, the hydrogen volume in the radiation gas sample is 0.0471ml (under one standard atmospheric pressure), and the hydrogen mass is 4.24 ×10 -6 g, the number of moles of hydrogen is 2.12×10 -6 mol. The above shows that the amount of hydrogen in the air is greatly increased after the yellow sea water filled with air is irradiated.

Abstract

The invention discloses a sampling device for detecting a radiation gas product, and a detection method thereof. The sampling device comprises a first pipeline communicated with a helium inlet, wherein the first pipeline is detachably communicated with a sealed glass container; the first pipeline is also communicated with a vacuumizing device and a balloon; the glass container is provided with a sealing structure and long-tube glass; a sample is arranged in the glass container; the long tube glass is communicated with the inner part of the glass container and is communicated with a first pipeline; the sealing structure comprises short tube glass communicated with the glass container; the opening of the short tube glass is provided with a sealing plug; the long tube glass is separated froma third pipeline; the long tube glass is communicated with a gas chromatograph through a fourth pipeline. The device can be put into a radiation field to serve as a glass sealing box for carrying outradiation, and also can be connected with the gas chromatograph to serve as a sample manufacturing device which carries out radiation gas detection. The device has the advantages of simpleness, high efficiency, low cost and good effect.

Description

technical field [0001] The invention belongs to the technical field of gas chromatography analysis of radiation gas, and in particular relates to a sample preparation device for detecting radiation gas products and a detection method thereof. Background technique [0002] In China, few people have been involved in the radiation water experiment, and no one has been involved in the design of the experimental device. In foreign countries, radiation water experiments have been used to study possible safety issues in the nuclear industry waste disposal process (Pastina, 2001; Fourdrin, 2013; Chupin, 2017) or to study the production of hydrogen as a clean energy source (Cecal, 2008). The radiation water experiment mainly includes two steps, sample radiation and detection of radiation products (gas). Radiation technology and gas detection technology are quite mature. The difficulty of this experiment is the preparation of the sample and how to take out the irradiated gas produc...
